Plywood Trail Replacement Wearing Out

The problem as of June 1 2013 - 100s of pounds of cyclists pounding these plywood sheets, day after day

About 1 3/4 miles from my house, along Four Mile Run on the bike (or mixed use) trail, Arlington County installed a temporary (one hopes) bypass storm drain pipe across the trail during the first week of May (2013). They built a ramp (or bridge) over this so that the trail is still usable. It is built out of plywood and the construction techniques leave something to be desired now that it is clear that it is going to be up for longer than say a week. The construction, not great in the first place, is gradually failing. Lawsuit alert!

The original execution had plain sheets of unpainted or treated plywood such that when it rained they were a bit slick. It struck me as obvious that the boards should be painted or treated with something and at that time throw some sand into the mix to add some traction. So I contacted this County with this brilliant observation:

My comment, made May 8 2013

Subject : WEBSITE COMMENT: Temp bridge over pipe -- ATTN: trails

Comments : On the bike trail along s glebe rd about 1/4 mile s of I-395 there is a new temporary plywood ramp over a pipe. This ramp is getting tire residue and is plain wood. When wet it is slick for bicycles. Can't you paint it and throw some sand on the paint for safety?

Thank you.

The County is fairly responsive. I was slightly amused by the notion that "exterior surfaces are slippery when wet" as being something they couldn't address but whatever.

First reply, May 9 2013:

Michael,

Thank you for writing about the ramp on the Four Mile Run Trail at South Glebe Road. Most exterior surfaces will be slippery when wet, but I will forward your observation to the unit who is working with the contractor. They may have a surfacing material with more traction for the ramp.

I was surprised (and I suppose pleased) to get a follow-up message soon after.

Second reply, May 10 2013:

Good Morning Michael,

Again, thank you for notifying trails of the condition of the bike trail ramp during the rain. The contractor has placed non-skid mats on the ramp to increase friction when bikes ride over it. Please see the attached picture for your reference. If you have any additional concerns in regards to the temporary bike ramp on S Glebe Rd, please do not hesitate to contact me.


Photo sent me by County showing how they solved the problem of slickness during rain (as of May 10)

This is a case of what happens when one (in this case me) is not very clear. I don't really see how strips like this solve the overall problem since there is plenty of area that is not covered by the traction material. And it doesn't address what is turning out to be more of a problem, which is that the untreated/unpainted boards are suffering under a higher level of pounding/usage than the County or this contractor imagined. I would not have guessed that a temporary structure of this quality was intended to serve this long - and apparently longer. Who knows how long.


June 1 - looks OK at this distance, although one railing clearly bowing in


Closer examination reveals somewhat wavy deck

The contractor chose to run the plywood longwise but it wasn't wide enough to cover the entire deck, so they have two sheets of plywood, one larger and one smaller, running side by side. Amazingly dumb. It would have been much better to run the plywood sideways so there is no "seam" running the same direction as the direction of travel.


Looking in other direction, clear that main sheet of plywood coming up

In the first picture in this blog post, another problem is clear, if you think about it. Cyclists are mostly are not used to riding on ramps like this and it isn't that wide - so they pretty much want to be in the middle (notwithstanding the little yellow striping that suggests this is some sort of miniature divided highway). Because many cyclists are apparently not used to be presented with problems of this sort, they try to cross in both directions at the same time as other cyclists or as pedestrians even though common sense would suggest that it is a bit risky. The County supplied signage warns as you approach in one direction "bump" (???) and "slow" (that's OK, I guess) in the other.

I will send the County a link to this blog post and perhaps they will make it better.

Or not. We'll see. . . . .

Steve Jobs: "Computers Are Like a Bicycle for Our Minds"

The Library of Congress was a partner to some television programs under the title "Memory & Imagination: Pathways to the Library of Congress" more than 20 years ago - they don't seem to be available on the LoC web site. Bits and pieces are available on YouTube, not surprisingly.

It turns out that the statement by Steve Jobs that, "computers are like a bicycle for our minds" came from one of those programs. But what was the context of this statement? What did he mean by that, really?


Jobs making his full statement on this subject

The snippet above from the original broadcast program fills out his statement with what he said, which is worth listening to (or reading, below). The video above includes some of the original program's credit sequence, so the first 20+ seconds include rather "heavy" (in the literal sense) music to suggest "culture and/or learning" (I guess) as the camera scans the Great Hall of the Library of Congress (that screams "culture and/or learning").

I think that one of the things that really separates us from the high primates is that, uh, we're tool builders. I read a, uh, study that measured the efficiency of locomotion for various species on the planet. The condor used the least energy to move a kilometer. And, uh, humans came in with a rather unimpressive showing about a third of the way down the list - it was not... not, uh, too proud a showing for the crown of creation. (Laughs) So, uh, that didn't look so good, but then somebody at Scientific American had the insight to test the efficiency of locomotion for a man on a bicycle - and a man on a bicycle, a human on a bicycle, blew the condor away. Completely off the top of the charts. And that's what a computer is to me. What a computer is to me is it's the most remarkable tool that we've ever come up with and it's the equivalent of a bicycle for our minds.

Perhaps showing I'm not very clever, the statement that a computer is "a bicycle for our minds" now makes more sense - in other words, it's a tool that we are smart enough to build that leverages what we are given (by God, or however humans came to be) and makes us more efficient - we can go faster, or (with the computer) be "smarter" (in some sense).

I am reminded of a previous blog post where I searched out a famous quote by Sir Arthur Conan Doyle about the psychological benefits of cycling - it was originally in Scientific American which Jobs mentions as his source of information for the efficiency of cycling as a form of locomotion. And I had not thought of Scientific American as a cycling publication! (The article Jobs mentioned may be the same one discussed in this blog entry about Ivan Illich and cycling.)

I like how Jobs tells this anecdote - he clearly is enjoying it. The creation of the bicycle saved mankind from being inferior to the condor, putting us on top in the locomotion department in nature. To me a question I have is what exactly we needed the computer for as far as putting us ahead of the other species with which we share the planet? Weren't we already ahead in this department, supposedly? But then we can be further ahead. Apparently.

Somewhat amusingly (for me), the filler footage (at around 1:23) used after Jobs declares that computers are a remarkable tool is of a Library of Congress staff person using one of the relatively few not very good PCs that the Library had in 1990. And I don't mean, "not very good" compared to PCs now, but compared to what was available then. Of course, some tools give you more leverage and others give you less - so I guess this would have been one of those "less leverage" tools.

1890s Memorial Day Bicycle Races

In the United States on Monday we have the holiday known as Memorial Day. As explained by Wikipedia, "Formerly known as Decoration Day, it originated after the American Civil War to commemorate the Union and Confederate soldiers who died in the Civil War."

I found the poster below in the Library of Congress Prints and Photographs Online Catalog (that also has posters ~ ~ ~ ). At the time the poster was created, in the 1890s, the holiday was still known as "Decoration Day."

This poster would have been deposited for Copyright protection at the Library of Congress but now is in the public domain. Created by Charles Arthur Cox, it is not clear where this race took place or in what year, other than during the 1890s (most likely the later half of the 1890s).

Perhaps not surprisingly, the Decoration Day holiday was associated with special sporting events such as bicycle races at this time. The Evening Star of Washington DC, for example, reports on preparations for the Decoration Day races for Memorial Day in 1895.

BICYCLE RACE MEET

To Be Held Tomorrow Under the Columbia Club Auspices.

It is Expected That the Fastest Time Ever Made in the District Will Be Recorded.

The big Decoration day bicycle race meet held under the auspices of the Columbia Athletic Club will begin tomorrow morning promptly at 10 o'clock on Columbian field. Everything is ready for the occasion, and with hard work and favorable weather the track has been put in first-class condition and it may be put down as an assured fact that the fastest time ever made in the District will be scored tomorrow.

"Jet Roars over Bicycle Path near Washington's Nation[al] Airport"

Jet Roars over Bicycle Path near Washington's Nation[al] Airport.

From the National Archives and Records Administration (NARA) "Commons" space on Flickr. Flickr redid their interface overnight and the opening screen features what they call "The Commons" more. I assume that rendering the name of the airport as "Nation Airport" rather than National Airport (now Reagan National Airport) is a typo. ??? It's also slightly odd that the subject heading is for Washington DC without one for Arlington VA. While it is nominally Washington's airport it isn't in Washington.

Now the noise level is much lower from jet engines than in 1972. The 727 was known for being particularly noisey. At least there is some progress. . . And one doesn't see 727s any more - not all gone I'm sure but not used here.

"Biggest Bicycle Ever Built"? DC Newspaper 1897

Sometimes I come across things in older newspapers that I can't figure out. In the 'Wheels and Riders' page for the February 6 1897 issue of the Washington newspaper the Evening Star in 1897 there is a line drawing captioned "Biggest Bicycle Ever Built" that seems to be set in Washington.


The illustration showing the "Biggest Bicycle Ever Built"

I spent some time reading the articles surrounding the illustration but they make no mention of this bicycle. In newspapers at this time there was a fair amount of "filler" such as short jokes or anecdotes that don't necessarily track with the rest of the nearby material. Is this some kind of filler? Or it is reference to something real?

Washington, May, Cycling - in 1897

In the late 1890s, at the height of the "bicycle craze," some newspapers catered to their bicycle-mad readers by providing pages of dedicated cycling coverage on a regular basis. The Washington (DC) "Evening Star" had full page coverage of cycling, from local events and activities to races nearby and in other cities, as well as descriptions of new equipment - such pages over time were titled "Wheels & Riders" and "Wheels & Wheelmen."



A full page for cyclists in a Washington newspaper of 1897

The full page of articles from this May 22 issue, for example, covers the problem of crowds of riders on the weekend during good weather in May, and particularly police activities to control "scorchers."

According to the forecast of the weather slight rains are predicted for tomorrow. Last Sunday the weather was propitious in all respects for cycling. The light wind which prevailed the greater part of the day was just sufficient to keep the riders from becoming overheated. An unusually large number of cyclists were out on the roads. Maying parties were numerous and the hunt for the pretty wild flowers seemed to have particular fascination for the riders of the fair sex.

A "Maying party" was apparently just a picnic organized in May, according to "The Complete Hostess" of 1912.

. . . It is understood that the entire police cycle squad of the city have been ordered out on the Conduit road for duty tomorrow. They will endeavor to suppress the scorchers. and in this laudable undertaking they will have the support of the largest number of riders for pleasure purposes only. The arrest of a dozen or more scorchers would have a salutary effect, and doubtless put a stop to the practice for a week or so at least.

In this connection an amusing story is told of an occurrence that happened last Sunday. There were several tandems coming down the road at an eighteen-mile-an-hour gait, when one of the mounted members of the county police force called upon them to slacken their speed. Just as the scorchers passed by the policeman he heard one of the riders urge the others to keep on, telling them that the cop would never be able to catch them. In this the riders were sadly mistaken. The policeman quickly jumped on his horse, and in an instant was after the two tandem teams. With a l00 yards start of him the policeman caught the men inside of 300 yards, and fearing the result the riders of both tandems ran their machine over in a ditch, fortunately escaping injury. They were a very humble and penitent set, and, after considerable pleading, were allowed to go. According to the policeman's theory he can overtake any scorcher on the road. They can cover a mile in something like 2.50 says he, while he would not use a horse which could not run the distance in two minutes or under, for cases of emergency. The other members of the mounted county police force are equally well mounted.

A full page for cyclists from the Washington "Evening Star" in February 1897, in advance or the "cycling season"

These pages often give statistical information about the scale of cycling at the time, which is interesting up to the point where I realize I don't have much of a sense of the modern day equivalents. Also, in 1897 most of the bicycles that would have been purchased would have been used, while today most bicycles in America are in some version of long term storage most of the time. The page from which the graphic shown above was taken includes this:

With a basis of 40,000 wheelmen and wheel women in the city, the following would represent the aggregate cost of bicycles in the District of Columbia alone:

Cost of wheels $3,200,000
Cost of lamps $ 100,000
Cost of bells $ 10,000
Cost of oil and wicks $ 10,000
Cost of costumes and caps $ 600,000
Cost of shoes $ 100,000
Cost of stockings $ 40,000
Cost of repairs $ 120,000
Cost of incidentals $ 200,000
Total outlay for cycling $4,380,000

Finding Mrs. L.C. Boardman on Her Bike, 1895

I found this item in the Prints and Photographs Online Catalog at the Library of Congress. I go into it from time to time to see if any new (old) bicycle photographs have been added or if I have missed something interesting by not looking close enough in the past.

In examining this photo from 1895 as presented by PPOC I have several comments:

* The person who put this online didn't look at the label on the photograph closely or made a keying error, thus the subject's name is recorded as "Bordman" not "Boardman."

* This digital reproduction was made not from the original print that was deposited at the Library of Congress on Copyright but from a negative that was made in order to satisfy a Photoduplication request some time much later. So this is a copy of a copy, which is one reason it may be somewhat less than sharp (although it is hard to tell).

* The 40 kb JPEG, which for some reason is only available on site at the Library of Congress although it is not really possible for it not to be in the public domain, isn't very good because the quality was greatly reduced in creating an image that loads quickly. Having just one JPEG derivative was more a common practice some years ago but isn't now.

* The TIFF image has some issues with the black areas on her dress, "blocking up," but otherwise the most detailed JPEG in my Flickr set shows details of the bicycle and her cycling attire otherwise. I produced an 850 kb JPEG from the TIFF on the LC site.

I like her derby hat.


Mr. L.C. Boardman, it turns out, was active in the "good roads" movement

Mrs. Boardman may have been photographed in 1895 on a bicycle but after the turn of the century, her husband was apparently active in trying to improve roads for automobiles. In the text above, he is described as giving a lecture to the Automobile Club of America. Oh well. . .
